Treatment liquid for screen printing plate and method for treating screen printing plate

Abstract

A treatment liquid for a screen printing plate is disclosed that contains a resin, water, a surfactant A, and a surfactant B having a solubility in water lower than a solubility of the surfactant A in water. A method for treating a screen printing plate is also disclosed.

What is claimed is: 
     
       1. A treatment liquid for a screen printing plate, the treatment liquid comprising a resin, water, a surfactant A, and a surfactant B having a solubility in water lower than a solubility of the surfactant A in water,
 wherein the surfactant A and the surfactant B are each independently selected from the group consisting of acetylene glycol-based surfactants, polyoxyethylene alkyl ether-based surfactants, polyoxypropylene alkyl ether-based surfactants, polyoxyethylene alkyl phenyl ether-based surfactants, polyoxypropylene alkyl phenyl ether-based surfactants, polyoxyethylene fatty acid ester-based surfactants, polyoxypropylene fatty acid ester-based surfactants, sorbitan fatty acid ester-based surfactants, polyoxyethylene sorbitan fatty acid ester-based surfactants, polyoxyethylene sorbitol fatty acid ester-based surfactants, and glycerol fatty acid ester-based surfactants, 
 wherein the solubility of the surfactant A in water at 23° C. is 1 g/100 g or greater, and the solubility of the surfactant B in water at 23° C. is less than 1 g/100 g. 
 
     
     
       2. The treatment liquid for a screen printing plate according to  claim 1 , wherein the surfactant A is an acetylene glycol-based surfactant. 
     
     
       3. The treatment liquid for a screen printing plate according to  claim 1 , wherein a minimum film forming temperature of the resin is 23° C. or lower. 
     
     
       4. The treatment liquid for a screen printing plate according to  claim 1 , further comprising silica. 
     
     
       5. The treatment liquid for a screen printing plate according to  claim 1 , further comprising at least one selected from the group consisting of a polyether-modified silicone-based compound and a (meth)acrylic-modified silicone-based compound. 
     
     
       6. The treatment liquid for a screen printing plate according to  claim 1 , wherein the surfactant A and the surfactant B are each independently selected from the group consisting of acetylene glycol-based surfactants and polyoxyethylene alkyl ether-based surfactants. 
     
     
       7. The treatment liquid for a screen printing plate according to  claim 5 , wherein the at least one selected from the group consisting of a polyether-modified silicone-based compound and a (meth)acrylic-modified silicone-based compound comprises at least one selected from the group consisting of polyether-modified silicone-based surfactants and (meth)acrylic-modified silicone-based resins. 
     
     
       8. A method for treating a screen printing plate, the method comprising treating a screen printing plate with the treatment liquid for a screen printing plate according to  claim 1 . 
     
     
       9. The method for treating a screen printing plate according to  claim 8 , wherein the surfactant A is an acetylene glycol-based surfactant. 
     
     
       10. The method for treating a screen printing plate according to  claim 8 , wherein a minimum film forming temperature of the resin is 23° C. or lower. 
     
     
       11. The method for treating a screen printing plate according to  claim 8 , wherein the treatment liquid for a screen printing plate further comprises silica. 
     
     
       12. The method for treating a screen printing plate according to  claim 8 , wherein the treatment liquid for a screen printing plate further comprises at least one selected from the group consisting of a polyether-modified silicone-based compound and a (meth)acrylic-modified silicone-based compound. 
     
     
       13. The method for treating a screen printing plate according to  claim 8 , wherein the surfactant A and the surfactant B are each independently selected from the group consisting of acetylene glycol-based surfactants and polyoxyethylene alkyl ether-based surfactants. 
     
     
       14. The method for treating a screen printing plate according  claim 12 , wherein the at least one selected from the group consisting of a polyether-modified silicone-based compound and a (meth)acrylic-modified silicone-based compound comprises at least one selected from the group consisting of polyether-modified silicone-based surfactants and (meth)acrylic-modified silicone-based resins.
